Teaching a lab or a class that is geared toward sensors? There are a number of low cost evaulation board offered by a number of vendors which are easy to use and help teach.
The NPA series is the latest product offered by General Electric. The NPA series is available in a mV, amplified and a digital output
Board level pressure sensors are not made to be used with all types of media. To understand which media will work with piezoresistive pressures you need to understand how the sensors are made.
The differential op amp circuit shown on GE/NovaSensor NPC-1210 and the IC Sensor 1210A datasheet is often questioned. This Blog answers some of these common questions.
If you looking to make a instrumentation amplifier for a pressure sensor, you might want to consider the LTC1167. This single resistor gain programmable op amp, will save your time and increase performance.
Looking for a circuit schematic to build an altimeter? Try these two circuits created by the Linear Technology application team! Both designs use GE/NovaSensor pressure sensors - The NPC-1220 and the NPP301 sensor.
If you read the datasheet on GE/NovaSensor and the Measurement Specialties 1210A pressure sensors, at first glance the two parts appear to be drop in replacements for each other (fit, form and function). However, there is one difference which is not shown nor highlighted on either datasheets.
Thinking that pressure sensors can be put thru standard solder reflow operations? Think again. Sensors are not standard integrated circuits. Some precautions need to be taken.
Looking for a couple fo parts to get you thru a quick prototype or need a small number of parts to get you through a production run and you can not find the exact part you need in stock? You might consider one of these options.
Trying to order a GE NovaSensor NPC-1210-xxxD-xN pressure sesnor and told that that part number is not valid and you should order the NPC-1210-xxxG-xN. Here is an explaination.
